Plot

[edit]

Juzo Ogami is a 40-year-old who works for the Z.O.O. assassin syndicate as their prized hitman. During a job taking out criminals working with the genetic manipulation company Mitsuoka Pharmaceuticals, Ogami is stung by a wasp that modifies his DNA, regressing his age to that of when he was 12. Unable to resume work as a hitman due to his stature, the head of Z.O.O. gives Ogami another assignment while they work on an antidote: attend a middle school the head's daughter is applying to and judge if it is safe. Ogami, due to having no formal education, turns out to love middle school, and must balance his time as a student and an assassin. He must also deal with Noren Mitsuoka, the heiress of Mitsuoka Pharmaceuticals, who may be the key to figuring out how to age Ogami back to normal.

Characters

[edit]
Juzo Ogami (大狼 十三, Ōgami Jūzō)
The main protagonist. He is a 40-year old assassin who is aged back to 12-years old after being stung by a mysterious wasp during a mission. Initially, he didn't like the idea of going back to middle school, but he soon came to enjoy it. His skill with a handgun has earned him the nickname "Demon's Left Hand".
Noren Mitsuoka (蜜岡ノレン, Mitsuoka Noren)
The main heroine. She is a middle school student and the daughter of Mitsuoka Pharmaceuticals founder. She is constantly hit on by other students, causing her to initially hate men, before befriending Ogami. She helps out her Uncle at his Ramen Shop, and wishes to takeover it when he retires.
Kotatsu Nekota (猫田 コタツ, Nekota Kotatsu)
Ogami's partner. Although not nearly as experienced as Ogami, he is skilled with technology, and has more skill in cooking and house care. He created the pair of glasses that Ogami wears that acts as a camera and radio for him.
